api record

Reference layer for prediction markets. Judges whether a Kalshi or Polymarket price can be trusted: every market carries a Resolution Clarity Grade (A/B/C), the committed resolution source is named with provenance where one exists (the absence is graded too — that gap is the point), and the same question across venues is linked by a venue-independent question_id with live cross-venue prices (also_on). Read-only reference data; not trading advice.

_ what it can do 3 tools
3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • event_search reads unknown never probed

    Free-text search across graded prediction-market events on Kalshi and Polymarket. Returns per-event grade mix, venues, prices, and the canonical CM ids to cite.

    prediction-marketssearchevents

  • market_trust_lookup reads unknown never probed

    Given a market id (CM-MKT-…), a Kalshi ticker, or a market URL (Kalshi URLs resolve; for Polymarket pass the conditionId): the Resolution Clarity Grade, the committed resolution source and its provenance, settlement status, latest price, and cross-venue twins.

    prediction-marketsresolutionprovenancereference-data

  • upcoming_catalysts reads unknown never probed

    Dated calendar of scheduled events (Fed decisions, CPI and jobs releases, earnings) that graded prediction markets resolve against, over the next N days. Each entry carries the date, type, and source URL.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your agent card — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 108faae85b4f8e99.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/108faae85b4f8e99/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/108faae85b4f8e99/badge.svg)](https://brick.blue/agent/108faae85b4f8e99?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

_ also on clearmarket.fyi 1 entry

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
